Q. A compound is made by mixing cobalt(III) nitrite and potassium nitrite solutions in the ratio of $1 : 3.$ The aqueous solution of the compound showed $4$ particles per molecule whereas molar conductivity reveals the presence of six electrical charges. The formula of the compound is :

$C o (N O_{2})_{3} .2 K N O_{2}$

$C o (N O_{2})_{3} .3 K N O_{2}$

$K_{3} [C o (N O_{2})_{6}]$

$K [C o (N O_{2})_{4}]$

$C o (N O_{2})_{3} + potassium cobalt nitrite 3 K N O_{2} \to K_{3} [C o (N O_{2})_{6}]$
